Persuade hospital department to acquire coolant (6)
I believe the answer is:
entice
'persuade' is the definition.
(I've seen this before)
'hospital department to acquire coolant' is the wordplay.
'hospital department' becomes 'ENT' (Ear, Nose and Throat).
'to acquire coolant' becomes 'ice' (I can't justify this - if you can you should give a lot more credence to this answer).
'ent'+'ice'='ENTICE'
Can you help me to learn more?
(Other definitions for entice that I've seen before include "Coax" , "Tempt with inducement" , "Tempt with promises of reward" , "Lure, beguile" , "draw" .)
